JOHN W. IBURKETT, OF KANSAS CITY, KANSAS, ASSIGNOR TO THE KANSAS CITYHAY PRESS COMPANY, A CORPORATION OF MISSOURI.

BALING-PRESS.

To all whom it may concern:

Be it known that I, JOHN WV. BURKETT, a citizen of the United States ofAmerica, residing at Kansas City, in the county of WVyandotte and Stateof Kansas, have invented certain new and useful Improvements inBaling-Presses; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers to make and use the same, reference being had to the accompanyingdrawings, forming a part of this specification.

The object of the invention primarily is to feed the loose balingmaterial deposited at the feed opening to the feed chamber within thechamber, with a far reach to the material and a close draw to the headblock. Second to deposit the material in folds within the chamber and incontact with the outer end of the retracted headblock. Third: to controlat will the density of the compressed material and, fourth to controlthe tension to the retainers.

The invention consists in the novel construction and combination ofparts such as will be first fully described and then specificallypointed out in the claims.

In the drawings, Figure 1, is a side view of a power operated balingpress, embodying the invention, mounted upon its supporting wheels andin readiness for operation. Fig. 2, is a plan view of the press as seenin Fig. l, a portion of the upper angle bars and top plate being brokenaway to show the compression plate. Fig. 3, is a longitudinal verticalsectional view of the press taken on the line X X on Fig. 1, thesupporting wheels being removed. Fig. 1 is a detail view in perspectiveof one of the retainer supporting plates showing the adjustable tension.Fig. 5, is a transverse vertical sectional view of the delivery end ofthe press taken on the line Y. Y. on Fig. 2. Fig. 6 is a detail view inperspective of the dropping device for the division blocks. Fig. 7 is adetail rear end view of the main frame showing the axle support and thegear mechanism.

Similar numerals of references indicate corresponding parts in all thefigures of the drawings.

Referring to the drawings 10 indicates the main frame of the power presswhich consists of the upper angle bars 12, and the lower angle bars 14,at the four corners of Specification of Letters Patent.

the frame, these bars extending in a longitudinal direction the entirelength of the press. IVithin these angle bars is a rectangular shapedopening 13, of the proper di mensions for baling the material which alsoextends the length of the press.

At the rear end of the press and secured rigidly to the outer surfacesand rear ends of the angle bars 12, and 14: are the vertical plates 15.\Vith the upper and lower ends of these plates is connected therespective upper and lower transverse plates l6 and 16 see Figs. 1 and7, which bind the parts of the frame firmly together.

The rear end of the press is mounted upon a-transverse axle beam 17,between which beam and the transverse plate 16, are swivel wheels 18 and19 secured rigidly to the respective beam and plate and through whichplate 16, and the wheels 18 and 19 extends the king bolt 20 which alsoextends through the beam 17. Through the axle beam 17, extends the axle21 upon the outer ends of which axle are the supporting wheels 22. At apoint beneath the lower angle bars 14-, of the press about two thirdsthe distance from the rear end is a transverse axle beam 23, throughwhich extends an axle 24, upon the ends of which axle are the supportingwheels 25. ith the rear axle beam 17, is connected the draft beam 26, bymeans of which the press is moved in position by suitable traction powerapplied thereto.

lVithin the frame 10 of the press is a bottom plate 27, which extends inwidth from the inner surface of one of the longitudinal angle bars 11,to the lower surface of the parallel angle bar 11, and in length fromthe forward to the rear end of the press about two thirds of thedistance.

At a point intermediate the ends of the frame 10 of the press, is thefeed chamber 28, upon the sides of which are the vertical plates 29,bolted at 29 to the inner surfaces of the upper and lower angle bars 12and 14. These plates 29 extend to a position a short distance beyond avertical line extending through the axle beam 24, toward the forward endof frame 10 and rearwardly to a position a short distance forward of therear end of the bottom plate 27.

30 is the top plate of the frame 10, which plate extends from theforward ends of the frame 10, rearwardly to a point intermediate theends of said frame, its rear end forming the forward end of the feedopening 31, for the material to be baled, within the baling chamber 28.The top plate 30, extends in width a short distance beyond the verticalouter surface of the angle bar 12, 011 one side of frame 10, and acorresponding distance beyond the line of the outer surface of the anglebar 12, upon the other side of the said frame and is riveted to saidangle bars.

\Vithin the baling chamber 28 and movable upon the bottom plate 27, isthe head block or plunger 32, which as seen in Fig. 3 is cast hollow,with a forward compressing end 33, the rear end being open. In the sidesof'the head block and forward end are depressions 32*. The outer surfaceof the top 34 of the head block comes nearly into contact with the innersurface of the angle bars, 12, and in the reciprocal movements ofthehead block within the baling chamber passes beneath the feed opening 31.Upon the inner surface of the forward compressing end of the head blockis a perforate lug 35, located at a point intermediate the top andbottom walls of the head block, and with the said lug is pivotallyconnected at 36, the forward end of the pitman 37. The

located within the opening 13, of the frame 10, of the press and atpoints about equidistant from each other and the angle bars. 12 and 14,upon the respective sides of the said frame these gear wheels extendinga considerable distance below the line of the lower angle bars 14 andalso above the upper angle bars 12. Upon these wheels are stud shafts39, which shafts extend outwardly and are j ournaled at their outwardends in the upright plates or supports 40, which supports or plates arebolted at 40 to the inner surfaces and vertical portions of the upperand lower angle bars 12, and 14 of the frame 10 at a point a shortdistance inwardly from the rear end of said. frame. Upon the gear wheels38 near the periphery are cast the lugs 41, through which lugs extend acrank wristpin 42, and: with which pin is pivotally connected the. rearend of the pitman 37.

Upon the upper surface of the angle bars 12 and bolted thereto at therear end of frame 10, are the shaft supporting blocks 43, which extend aconsiderable distance for-. ward of the rear end of said frame. Upon,said blocks 43, adjacent to the rear end of: the frame 10 is journaledin the journal: boxes 44, a transverse shaft 45, the ends of: whichshaft extend outwardly a short distance from the line of the outersurface of; the supporting blocks 43 and upon the said ends of the shaftare the gear wheels 46. Upon said shaft 45 between the respectivejournal boxes 44 are the small gear wheels 47, with which mesh the cogson the large gear wheels 38 carrying the pitman 37. Upon the supportingblocks 43, a short distance forward of shaft 45 and journaled in thejournal boxes 48, on said block is a transverse shaft 49 considerablylonger than shaft 45 upon the ends of which shaft are the balance wheels50 and 51. Upon the shaft '49 outwardly from the journal boxes 48 aresmall gear wheels 52, with which mesh the cogs on the large gear wheels46, on the shaft 45, on the supporting blocks 43. On the outer end ofshaft 49, carrying the balance wheel 50 is a band wheel 53 over whichextends a belt 54, which belt is connected with the band wheel upon anengine not shown) and through which belt is communicated the power tooperate the press.

The feeder for feeding the loose baling 'material into the balingchamber consists of 55, are the blocks 57 through which blocks and thesaid portion of the bar which form the feeder head extend the securingbolts 58 upon which are the nuts 59 these blocks 57,

serving to increase the width of the bent end of the portion of the barand form a feeder head of considerable proportions. Upon the feeder headare two material grasping plates 60 and 61, secured rigidly at theirinner ends to the respective outer and inner portions of said blocks 57transversely to the portion 56 of said bar The outer ends of theseplates extend a short distance beyond the outer ends of the blocks 57,and are serrated at 62. Upon the outer surface and upper end of theouter plate 60 is secured rigidly a material gathering plate 63, theouter end of which plate is inclined forwardly and downwardly from saidplate 60.

' In order to effect the feeding movement of the feeding head of thefeeder bar 55, upon the shaft 49, on the shaft supporting blocks 43, areloosely connected the inner ends of the cast link 64 which is A shape inform, the outer ends of which link are bent toward each other andpivotally connected by the bolt 56*, with the bar 55, at a point a shortdistance below the curved portion 55 of the bar 55, the length of thelink 64, being of a suitable length to give the desired movement of thefeeder head in and out of the feed chamber so that when the pitman is ina retracted position as seen in Fig. 3, the links (54, which constitutea movable fulcrum for beam permit of the entrance of the feeder headwithin the lower portion of the baling chamber and the gathering plates60, and 61 to come within the proper distance of the bottom plate 27, todraw the material into folds in the retraction of the head block and thedownward movement of the feeder head.

It will be observed that the forward end of the frame 10 of the press iscapable of compression and in order to regulate this compression so thatthe baled material may be given a density so as to increase the weightof a bale a U shaped rod 65 is extended beneath, the angle bars 14, at apoint near the forward ends of the bars, the ends 65* of which rodextend upwardly upon the sides of the angle bars 12, and 1 1 through theoutwardly extended portions of the top plate 30, and terminate a shortdistance above said plate. The upper ends of these rods are screwthreaded and upon said ends are nuts 66, with which nuts are connectedspoked wheels 67, the nuts when turned upon the rods 65, binding uponthe top plate 30, and imparting rigidity to the rod. Upon these rods 65,are socket plates 68, fitting said rods and upon the inner side of saidrods are the compression plates (59, secured by the bolts 70 to thesocket plates 68, the rear ends of which plates at 71, are curvedoutwardly in a slight degree so as to clear the sides of the baledmaterial. Extending around the lower vertical portions of the rod 65,beneath and supporting the plate 70 are the thimbles 69%.

Upon the outer vertical surface of the angle bars 12, and 14 on bothsides of the frame 10 at a point adjacent to the rear end of the topplate 30 are bolted the retainer supporting plates 72, which arerectangular in shape these plates as shown having side and end plates 73and 74, respectively extending outwardly a short distance. With theinner surface of the sides 73, in the dii'ection of the rear end of theframe 10 are secured the lugs 75. To these lugs are pivoted at 76, theforward ends of the retainer bars 77. Upon the said forward ends of bars7 7, are rigidly connected the rectangular blocks 78, the inner surfaceof which blocks are inclined rearwardly in a slight degree as at 78*.These blocks 78 extend through openings 79, in the plates 72, and alsothrough openings 80, in the plates 29, which form the sides to thebaling chamber 28, as seen on Fig. 3, the extension of said retainingblocks within the chamber being sufficient to retard the backwardmovement of the compressed material. Upon each plate 72, are shown upperand lower retainer bars 77, which are connected together by a.connecting bar 80. Through said bar 80 extends a screw threaded bolt 81,its

head 82, being secured rigidly to the plate 72. Extending around thebolt 80 is a spiral spring 83, its inner end bearing on the bar 80. Uponthe bolt 81 is a nut 81, which bears adjustably upon the outer end ofthe spring 83. The adjustment is therefore quickly made upon the nut andconsequently increasing the tension of the spring so that the retainersresist the passage of the compressed material when the density of thebale is increased and the compressed material requires more resistance.

For the purpose of preventing the scattering of the material to be baledand giving it a tendency toward the feed opening a table 85, is madeconsiderably wider than the frame 10, of the press and which issupported upon the transverse bars 86, one of which bars is locatedabove a point in a vertical line with the head block 32, in itsretracted position and the other bar at a point about two thirds thedistance from the rear end of the frame 10 of the press. In the table isan opening 87, of the same width as, the feed opening to the balingchamber 28, the forward end of which opening is in a vertical line withthe rear end 31, of the top plate 30 and the forward end of said openingextends rearwardly to the transverse bar 86. At the forward end of thetable is a raised plate 88, the rear end of which plate is inclinedtoward and terminating at the forward end of the opening 87, in thetable 85.

89 indicates a division board dropper for the division blocks 90separating the compressed material into bales of the usual length withinthe press. The dropper consists of a fiat plate 91, see Fig. 6 of thewidth of the feed opening in the table 85. This plate is provided withsides 92 which gradually decrease in width toward the upper end of theplate. The lower end of the plate is pivoted by the pivots 93 to theupper surface of the angle bars, 12 at a point in a vertical line withthe forward end 33, of the head block when said head block is in aretracted position. With the upper end of the plate 91, are connectedthe handles 94, which extend upwardly a considerable distance and alsobent outwardly so as to be in convenient reach of the hand of theoperator.

In operation power from the engine through the belt 54 transmits motionto the shaft 19 and from said shaft through the gear wheels 52 and 4-6to shaft 45 and from said shaft to the gear wheels 38 through the gearwheels 17 on said shaft, and in the rotation of the gear wheels 38,rotary motion is communicated to its pitman 37 and reciprocatingmovement to the head block or plunger 32. In the forward movement of thehead block it traverses the feed chamber 28, its forward end passing aslight distance forward of a vertical line extending through theretainers, the depressions 32* in the side of the head block receivingthe retainers. The loose material to be baled is pitched on theinclined: plate 88, upon the table 85. In the forward movement of thehead block 32, from its forward position as seen in Fig. 1, with thepower expended to retract the pitman the lower pivoted end of the bar55, of the feeder moves re-arwardly while its upper end is pivotallyheld and fulcrumed on the link 64 and the feeder head moves downwardlyand inwardly within the feed chamber with a traverse movement impartedto the feeder head in the crank movement of thence with a rear traversemovement the feeder head carries the material against the forward end 33of the head block, which head block is now fully retracted and thepitman upon the dead center with the axis of the wheels 38. Assoon asthe pitman passes the dead center of the wheels in the continuedrotation of said wheels the head block moves forward and the feederhead: and link move upwardly into the dotted position seen in the Fig.3', the head block forcing the charge of the material past the retainerswhich yield to the compressed mate-- rial and prevents its return intothe feed chamber. In the downward movement of the feeder head the plate63 gathers the material and carries the loose ends down-- wardly withinthe feed chamber and these loose ends are folded in the repeated chargescompressed by the head block. In increasing the density of the materialthe wheels 67 operating the nuts 66, at the forward end of the frame 10,are turned so as to increase the pressure of the nuts on the top plate80, and thereby increasing the rigidity of the rod 65, and drawing inthe proper degree the upper and lower angle bars 12, and 14, toward eachother. The lateral expansion is resisted by the plates 70', which areheld in place by the rigidity of the rod 65. The resisted movement ofthe compressed material past these plates (39 compels increased power tobe applied to the head block and thus crowding the material into lessspace within the press. Upon the compression of a desired quantity ofthe material within the baling chamber sufficient to form a bale adivision block 90 is placed in the chopper 91 and upon the return of thehead block 32, the handles 9%, are seized by the hand of the operator,and the dropper is moved. forward on the pivots 93, and the divisionblock falls within the baling chamber 28 in front of the head block andupon the forward movement of said head block the division block isforced upon the compressed material and past the retainers 78. Besidesincreasing the baling capacity of the press the feeder head makes acompact fold of the material previous to the compression in the balingchamber.

It is obvious that the power to operate the pitman may be applied directto the wheels 38, the speed however of the wheels is controlled by thegear which gives leverage power for operating the pitman.
